The 46-year-old, who is wanted in the Baltic state on terrorism charges and for attempting to get weapons, ammunition and explosives, including detonators and timers, appeared before the High Court in Dublin for the brief hearing.

It is alleged he conspired with three others between the end of 2006 and 2007 to obtain and smuggle weapons.

His brother Michael Campbell is behind bars in Lithuania linked to the same trafficking racket. Irmantas Mikelionis, deputy head prosecutor of Vilnius, said investigators hope to bring a case against him in March.

Campbell, who is among five dissident republicans being sued by relatives of the victims of the Omagh bomb for £10m (€15m), plans to contest the European arrest warrant.
